TO ALL WHOM IT MAY GONCERN:

Beit known that I, NATHANIEL T. EDSON, of Newr Orleans, parish of Orleans, tate of Louisiana, have invented a new and improved mode of making Paddle-lllhsels for propelling vessels; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of referencemarked thereon. j Y

The nature of my invention consists in so constructing the wheel and its loats or buckets that they will retain a vertical position whilst in the water. v i

To enable others to make and use my invention, I will describe its construction and operation.

Figure 2 is a perspective view of the Wheel complete. l v

A and B are the wheels, to which the ioats C, D, and E are pivoted. F is a wheel to hold the oatsby their arms Gin a vertical position. Aconnecton is formed between the arms Gr and the wheel F by passing the arms through a slot or orifice formed in the swivel-blocks H, one end of the blocks being rounded, and passing through the rim of wheel F, which arrangement admits of a revolving of the Wheels, and a slip of .the arms in the blocks sufcient to adapt themselves to their different positions iu the revolving of the wheel. Shaft I may have an outside bearing, whereby the wheel, with equal facility, can be applied to the stern of vessels. Wheel F is supported by or rests upon rollers a a a', which rollers are attached to th'e timber on which the shaft I rests. The centre of the wheel is in the rear of the shaft I, and has firmly attached to it cog-wheel ZJ".l There is attached to the shaft I, outside of its-bearing, or inside ofv its inner bearing, a cog-wheel, e', which wheel is of the same dimension, and contains the same number of eogs, as wheel 6.. Two cog-wheels, d', attached. to one shaft, which shaft forms a journal for both wheels, are so placed as to mesh intowheels and c', thereby securing to the float-wheels and arm-wheel F the same movement. The'arm of the float is attached to the sha-ft of the float on the outside of the wheel B, and at right angles with the Heats. The wheel F should be as near the size of the other wheels asVV convenient to make it. If of less diameter than the float-wheels, it should be placed suthciently below the shaft I to hold the ioat-arms horizontal when the floats are directly under the shaftI, and suicieutly aft of the shaft to bring the arms of the float-wheel and the arms of the arm-Wheel F parallel. To provide against accident to the above-described arrangement of' cog-wheels, the ends of the oatarms are provided with shoulders or lugs f', which limit the extent of the slip of the arms in the blocks H. g are springs, which will, with the lugs, retain the Heat-wheels and arm-wheel in their relative positions, if a removal or accident takes place with the above cog-wheel arrangement, the object of the springs being to relieve the parts of any unnatural strain caused by the imperfection of workmanship in the constructing of the wheel or otherwise.' i

p Figure 3 is a side elevatiouot` wheel F and its rollers a a a', shaft g, cog-wheel e', one of' the cog-wheels d', the other being hid by it, as is also cog-wheel b by Wheel F.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, isi 1. A combination of the iloat-arms with their lugs f', the Aswivel-blocks II, and wheels A B and F, whenA wheel F is constructed with arms firmly attached to its inner rim, and the float-arms placed at right angles with the floats.

2. I claim a combination of the cuff-wheels b and c when actinnand bein(r acted u on b corr-wheels d D o o a .o

and used with wheels A B and F, substantially as set forth and described.

N. T. EDSON.
